In fast national live+same day ratings, the premiere of FX's Terriers averaged 1.6 million total viewers and 659,000 adults 18-49 (a 0.5 rating) between 10p-11:13p. That's a pretty small start when compared to say, the series premiere of Sons of Anarchy in September of 2008 (2.5 million total viewers and 1.55 million adults 18-49).
Update: Things look even worse when compared to the premiere of Justified less than 6 months ago on March 16, 2010. It aired on a Tuesday at 10pm and averaged 4.16 million total viewers and 2.04 million adults 18-49.
Update 2: Should've included this originally as well - FX will try to bolster Terriers by running an encore after next week's Sons of Anarchy,
